Erlenmeyer Flasks

This flask was named after its inventor in 1861, but can also be called a conical flask. It has a narrow neck and expands as you go toward its base. This allows easy mixing and swirling of the flask without too much risk of spilling. The narrow opening also allows for the use of a rubber or glass stopper. It can easily be clamped to a ring stand (discussed below) as well as heated or shaken mechanically.

Once again the marks on the side are meant primarily for estimation rather than precision.

An important safety tip here is to NEVER heat this flask while it is capped.
